This invention relates 'to machines for use in the manufacture of shoesfor shaping uppers over lasts, and is herein illustrated as I, appliedto a pulling-over machine of a well-' known type many of thecharacteristic features of which are disclosed in Letters Patent No.1,029,387, granted on June 11, 1912, upon' an application of R. F.McFeely, although w it is-to be understood that the invention is not 10thus limited in its applicability. V

Pulling-over machines of i the above-mentioned type include in theirorganization upper-fastening mechanisms which are movable laterally ofthe shoe at the opposite sides 15 of the forepart into upper-fasteningpositions and are'constructed to drive at each side a plurality offasteningsspacedapart lengthwise of the shoe near the edge of the shoebottom. In order to position the different 29 fastenings at the properdistances from. the edge of the shoe bottom, Whatever may be the shapeand the position ofthe shoe, each side fastening mechanism is so mountedas to permit it to be turned about an axis extending heightwise of theshoe, and as the mechanism is moved toward upper-fastening position itis adjusted about its axis under control of the shoe. In machines ascommonly constructed heretofore such adjustment is effected indirectlyby the shoe through the action on the fastening mechanism ofshoeclamping means including a rubber pad previously applied in yieldingengagement with n the upper at the side of the shoe. An object of thepresent invention is to afford increased insurance that fastenings such,for example, as those above referred to, will be located in properrelation to the-shoe, and to this and other ends the invention providesnovel means for determining theposi tion of upper-fastening mechanism inits 'relationto the shoe prior to the driving of the fastenings. For thepurposes in-view, in the construction herein shown, each of theupperfastening mechanisms at the opposite sides of the shoe carriesmembers which are arranged to engage the side of the shoe indifferent'locations spaced apart lengthwise of the 7 shoe to adjust themechanism about its axis in accordance with the shape and position ofpointed out in the claims. i In the drawings,

the shoe, so that the shoeis directly effective to determine accuratelythe position of the mechanism. These members, as illi lstrated, are soconstructed and arranged as to engage the shoe positively, although insome. of its novel and useful aspects the invention is not limited topositive control of the upperfastening mechanism. Preferably,theshoeengaging members arespaced widely apart, to h facilitate quick andaccurate adjustment of the fastening mechanism under control of theshoe, the construction shown being such that the members engagetheshoerespectively at the front and at the rear of thegroupoffastenings and also at the front'and at the rear of the shoe-clampingmeans. ence with another feature, also, the shoeengaging members areadjustableto vary the relation ofthe fastenings tothe edge of the shoebottom. Y 1

The novel features of the invention will now be more particularlydescribed by reference to the accompanying drawings and Fig. 1 is a viewfrom the front of a machine In accordin Which the invention is embodied,showing portions of the upper-pulling, clamping and fastening mechanismsthat. operate at one Fig. 4 is a section on the line IVIV of; M

Fig. 5 isa perspective view of'a portion of the means whereby thefastening mechanism is'mounted for turning movement.

In view of the disclosure, in the above-mentioned and other priorLetters l fatent, of characteristics of the general organization ofmachines of the well known typeillus trated, only such parts as; it isnecessary to refer to for an understanding ofthis inv'en; tion areherein shown and will be particularly described. It will be understoodthat such a machine is provided with grippers for pulling the upper overthe last at the end of the toe and at the opposite sides of theforepart,

the toe gripper jaws being shown in section at 10 (Fig. 2) and the frontand rear pairs of side gripper jaws at 12 and 14, respectively. The shoeis supported against the pull of the grippers by a sole rest 16. Afterthe pull ing of the upper the shoe is engaged at each sideof theforepart by a pair of clamp mem- 'bers 18 and 20,'the member 18consisting of clamp members at each side are carried by an arm 22 thatis swung inwardly toward the shoe, the members being mounted;respectivelyv on slides 24 and 26 provided with rack teeth engaged by apinion 28, so'that the two I members adjust themselves to the shoe.

After the shoe has been clamped and supported as above described, themargin of the upperis wiped inwardly over the insole at the end ofthe-toe and the sides of the forepart and fastenings, customarily tacks,are

driven to fasten it in puiledeover position,

the grippers releasing the upper to permit these operations. The meansfor thus operating upon the upper at the end of the toe need not bedescribed in detail. For operating at the sides of the forepart thereare provided opposite side arms 30, a portion of one of which is shownin Fig; 1, these arms being mounted to swing laterally of the shoe andbeing swung inwardly toward the shoe at the proper time in the cycle ofthe machine, as fully described in the above-mentioned Letters Patent.Each arm 30 carries at its lower end a pair of wipers32 and 34 forwiping the margin of the upper inwardly over the insole, and means fordriving a plu- 'rality of tacks, herein shownas three in number, indifferent locations spaced apart along the side of the shoe bottom tofasten the upper in pulled-over position. The tack-drivingmeanscomprises drivers 36 arranged to cooperate with tack holders 38 and40 secured to a-block or holder 42 ,whichalso supports the wipers 32 and34. The wipers are controlled by means which need not be described indetail, since the construction is substantiallyas disclosed in LettersPatent No. 1,381,- 162, granted on June 14,1921, upon an applicationofU. J. Bouchard.

In common also with imachines heretofore in use, the construction shownis such that the upper-fastening mechanism on each of the side arms 30,together with the wipers 32 and 34, may be turned about an axisextending heightwise of the shoe to position the tacks in properrelation to the edge of the shoe bottom. For this purpose the block 42with its wipers and tack holders is-secured to the lower end of a member44 (Figs. 1 and 5) which is mounted in a recess in one side of the arm30, the securing means comprising a bolt 46 extending through lugs 48 onthe lower end of the member 44 and arranged to cooperate with ahook-shaped projection 50 which is formed on a plate integral with thetack holder 40 and partially embraces thebolt between the lugs. There isalso a tongue and groove connection 52 (Fig. 1) between the member 44and the tack holder 40, which assists in maintaining the parts in properrelation to oneanotherQ By a nut 54 on the bolt 46 the hook-shapedprojection 50 is clamped between the lugs 48. The member 44 at its upperend has a curved rib 56 proj ecting into a similarly curvedslot in thearm 30 and at its lower end it has curved slots 58 and 60 (Fig. 5).intowhich project ribs 62 and 64 (Fig. 1) formed on a plate 66 securedto the lower end of the arm 30. By this means the member 44 is held onthe arm 30 butpermitted to turn" about the common axis of curvature ofthe different ribs and slots. The tack drivers 36 also are so controlledas to permit {them to turn with the member 44, the drivers being. fastin a block 68 which is swiveled on a stud 7 0 on the lower end of adriver-operating bar 72 and is provided with a tongue 74 (Fig. 1)arranged to slidein a guideway between ribs 76 (Fig. 2) on the member44. To maintain the member 44 and the parts that move therewith normallyin a central position, while permitting them to turn as required, thereis a spring plunger 7 8, in the arm 30 having a wedge-shaped lower endarranged to cooperate with a correspond-' ingly shaped recess 80 in themember 44. The means for thus mounting and controlling the member 44 aregenerally similar to the disclosure of Letters Patent No. 1,029,387.

For adjusting each of the above-described upper-fastening mechanismsabout'its axis as the arm 30 which carries it is moved inwardly towardthe shoe, and thus to position the different tack holders and drivers inproper relation to the shoe for driving the different tacks at thedesired distances from the edge of the vshoe bottom, eachupper-fastening mechanism, in accordance with the present invention, isprovided with means for engaging the side of the shoe in locationsspaced a substantial distance apartlength wise of the shoe. This means,as illustrated, consists of two metal blocks 82 and 84 arranged toengage the side of the shoe respectively at the front and at the rear ofthe locations where the group of tacks are driven, and also atthe frontand at the rear of the clamping pad 18, each block being pivotallymounted on a pin 86 ona plunger 88 which supports-it, so that it mayturn about an axis extending heightwise of the shoe'and thus adjustitself to the contour of the side of the shoe. A small spring-controlledplunger within each plunger 88 is arranged to contact with a straightsurface on the block 82 or 84 and thus normally to maintain ityieldingly in a centralizedvposition. Each plunger 88 is mounted in alateral extension of the holde'r42 and is adjustable laterally of theshoe by means of a screw 92 which is threaded in the holder. A spring94, connected at one end to the pin 86 and at its other end to a screw96 in the holder 42 main-.

tains the plunger 88 yieldingly against the end of the screw 92.- Itwill be observed that the spring 94 connected to one of the plungers 88is above the plunger, while the spring connected to the otherplunger isarranged below it. Each screw 96 has on its end a stud 98 which projectsinto a slot in the plunger 88 to prevent the latter from turning. Eachscrew 92, moreover is held yieldingly in adjusted position-by aspring-pressed ball 100 (Fig. 4) which projects into one or the other oftwo slots 102 formed on opposite sides of the screw. a.

It will be seen that when each side arm 30 is swung inwardly toward theshoe, one or the other of the blocks 82, 84 engages the side of the shoeand causes the upper-fastening mechanism to turn about its axis untilboth the blocks are in contact with the shoe and thus determine theposition of the mechanism with respect to' movement about its axis andalso limit its bodily movement width wise. of the shoe. Such directcontrol of the fastening mechanism by the shoe, independently of theyieldable side-clamping means, serves to insure that the different tackswill be driven in proper relation to the edge of the shoe bottom,whatever may be the shape and position of the shoe. It will also beevident that by adjustment of one or both of the screws 92 the relationbe tween the tacks and the edge of the shoe bottom may be varied asdesired.
